Tropical Topics

Storm Eight remains tropically depressed, with top winds of 35 mph as of 5pm, continuing to move away from the Cape Verde Islands. It is still expected to become a hurricane as it turns more northwestward this weekend.

NOAA issued an unscheduled El Nino advisory today, announcing that increasing Pacific Ocean temperatures in the last 2 weeks have led to a weak El Nino condition. This event is expected to continue into 2007, and it has the potential to become moderate this winter. Expected El Nino effects this winter

include warmer-than-average temperatures over western and central Canada, and over the western and northern United States. Wetter-than-average conditions are likely over portions of the U.S. Gulf Coast and Florida, while drier-than-average conditions can be expected in the Ohio Valley and the Pacific Northwest.
